T all whom t may concern.'

Be it known that I, MAX P. GnnBiNG, a citizen of the United States, residing at Wentworth, in the county of Newton and State of Missouri, have invented a new and i useful Cultivator, of which the following is a specification.

This invention relates to cultivators and one of its objects is to provide a machine of this type having a balanced frame whereby the same can be manipulated easily, improved means being employed for adjustably connecting the cult-ivator` beams to the axle so that said beams can be quickly adjusted either vertically or laterally.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the lcombination and arrangement of parts and in the details `of constructionhereinafter de scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what isclaimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of 'the invention has been shown.

In said drawings Figure 1 is a side elevation of a portion of a cultivator and showing the parts constitutingthe present invention. Fig. 2 is a plan view of a cultivator having the present improvements combined therewith. Fig. 3 is an enlarged side elevation of the connection between the axle and one of the cultivator beams. Fig. 4 is a plan view of the parts shown in Fig. 3, a portion being shown in section.

Referring to the figures by characters of reference 1 designates an arched axle having opositely extending alining portions constitutingtrunnions or spindles2and arms 3 are adjustable angularly upon the outer ends of the spindles and extend rearwardly from the axle, each of these arms being formed, at its front end with a clamp 14 for engaging the spindle and at its rear or free end, with a laterally extending spindle 4 adapted to be engaged by the hub of one of the supporting Wheels 5. A draft tongue 6 is suitably secured to the middle portion of the arched axle l and braces 7 connect the sides of this beam to the sides of the arched axle and also to the front portion of the arms 3. Additional braces connect the rear portions of the arms 3 to the arched axle, as indicated at 8. An equalizer bar 9 is pivotally connected, at its center, to the tongue 6 and yokes 10 are pivotally connected to the end portions of this bar and extend forwardly therefrom, each yoke being pivotally attached to the upper end portion of a hanging draft bar l1. The lower end of the draft bar is connected, as by means of a link 12 and a rod 13, to the front end portion of the clamp 14 which connects the arms 3 to the spindle 2. The swingletrees 15 are connected to the respective draft bars 11, there being a series of apertures 16 within each of the bars so that the swingletrees can be adjousted to any desired positions upon the ars.

Line holders 17 and 18 are secured to the axle 1 and tongue 6 respectively, and guide the lines or reins. Secured to the lower face of the tongue 6 directly under the line holder 18 and preferably by means of the same bolt used for fastening' the holder 18 in place, is a rod 19 bent to form downwardly diverging hangers 20 each of which terminates in a hook. 21.

A sleeve 22 is mounted for rotation on each of the spindles 2 and is held against longitudinal displacement by arm 3 and the upstanding portion of the arched axle 1. Each sleeve has a 'broad face extending' throughout the length thereof and provided with a series of parallel longitudinally extending ribs 23 and an arm 24 extends from the inner end of each sleeve and is engaged by one end of a spring 25, the other end of the spring being engaged by a rod 26 adjustably mounted within an ear 27 extending from the arched axle 1. Thus it will be seen that spring 25 exerts a constant upward pull upon the arm 24 and the parts combined therewith.

A coupling in the form of a yoke 28 extends across the ribbed face 23 o-f each sleeve 22 and is provided, upon its rear or working face, with a plurality of parallel transversely extending ribs or serrati'ons 29. A U-bolt 30 embraces the sleeve 22 and has its ends extended through the yoke 28, these ends being engaged by nuts 31 or the like whereby the yoke 28 can be tightly clamped upon the ribbed face 23 of the sleeve and held against movement relative thereto. It will be apparent that, by providing the structure herein described, the yoke 28 can be adjusted longitudinally along the sleeve 22 and vertically relative thereto.

The rearwardly extending upper and lower arms 32 of the yoke have a bolt 33exv tending through them and through the tubular head 34 of a casting 35 in which one end of the tubular beam 36 of the cultivator is secured. This beam is angular in cross section. Any suit-able bearings may be provided between the arms 32 and the upper and lower ends of the head 34 so as to reduce fric-tion to the minimum during the rotation of the head 34 relative to the arms. The structure of this adjustable clevis made up of the parts 22 to 34 inclusive, has been clearly illustrated in Figs. 3 and 4.

Each of the beams 36 has a handle 37 adjustably connected to the rear end portion thereof and a bracket 3S stra'ddles and is con nected to the beam 36, there being a bolt 39 extending through the bracket and under the beam. The bracket has a toothed face 40 adapted to engage a co-rrespondingly toothed face 41 upon the base 42 of an arm 43 to which the handle 37 is connected. Base 42 is fastened to the bracket 38 by a bolt 44 and by providing the teeth 40 and 4] the handle is prevented from rotating relative to the bracket.

Should it be desired to elevate the beam 36 to which the cnltivator shovels are to be connected, said beam can be raised by means of the handle 37 and can be shifted laterally so as to engage and be supported by o-ne of the hooked ends 2l of the hangers or arms 20. The spring 25 of couise assists in the elevation of the cultivator beam inasmuch as this spring is connected to the arm 24 at a point back of the axis of rotation of the i 5 beam.

Importance is attached to the fact that the machine is practically balanced, this being due to the particular means for connecting the arched axle to the supporting wheels at points back of the vertical plane occupied by the axle. By thus balancing the machine the saine will operate more readily than where a large percentage of its weight is located back of the axle as ordinarily.

Each of the beams 36 has a yoke 45 straddling the same and secured thereto, said yoke being provided with suitable means fo-r attachin a plow standard`48 thereto. One end of tiis standard extends forwardly and is provided, at its front end, with suitable means for pivotally engaging a standard 54 which extends downwardly and rearwardlyV and has a fender 55 secured to its rear end and adapted to travel inside of the path of the plow carried by beam 48 so as yto protect plants from the soil overturned by the plow. A spring 56 is fixedly secured at one end and its other or free end is bent to form a hook 57 for engaging standard 54, thereby to hold the fender 55 pressed against the soil.

IVhat is claimed is Y v In -a cultivat-or the combination with an arched axle including a spindle, and a beam supported by the axle, of a rearwardly extending beam, a clevis secured thereto, a sleeve mounted for rotation on t-he spindle and having a front'engaging face formed with longitudinal projections, said clevis straddling the sleeve and having means 'for engaging the projections, means engaging the sleeve and clevis for holding said yoke against movement relative to the sleeve, a clam-p engaging the outer end portion of the spindle andl constituting means for holding the sleevev against displacementrelative tothe spindle, a crank arm integral with and extending rearwardly from the clamp for engaging a supporting wheel, Va connection between the clamp and the first named beam vfor reinforcing the clamp, a draft lever, and

a connection between said lever and the clamp, said connec-tionrbeing extended substantially in the same plane with the arm.

In testimony that I lclaimlthe foregoing as my own, I have hereto afli'xedmy signature in the presence of two witnesses.
